Trait Implementations

impl PartialEq for Union

fn eq(&self, __arg_0: &Union) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Union) -> bool

This method tests for !=.

impl Eq for Union

impl Hash for Union

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Debug for Union

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
